b all whom t may concern.'

Be it known that I, JOHN S. S. FULTON, of the eity of Chicago, in the State of Illinois, in the United States of America, for# merly of the town of Franklin, in the State of Pennsylvania, have invented a new and useful Improvement in Stove-Lids, of which the followingis a specification. n

My invention relates to improvements in stove lids. The main obj ect of my invention is to provide a lid through which pre-heated air is distributed over the top of the fire in order to secure a. more complete combustion` of the gases.

Another Object of my invention is to supply7 a lid made in two pieces, and having an upper side altogether similar: in' appearance to an ordinary stove lid.

A further object of my invention is to provide a. lid by means of which warmed air may be distributed evenly in all directions over the whole lire. l

The principle on which my lid operates is the same as that described in my United States VLetters Patent No. 711,04@ for improvements in locomotive boilers dated October 14th 1902.

My invention consists in the provision of a Vlid comprising an upper and a lower half held together by rivets or other suitable means. The lower half has a series of internal air passages leading from opposite the Vpoker hole, which preferably forms the inlet, to a central chamber from which small. l

outletsare so arranged that the warmed air is distributed evenly in all directions over the top of the fire.

My invention is more fully described with the aid of the accompanying drawings in which similar parts are similarly de-V scribed Figure 1 is a plan of the upper face of the lower portion, and

Fig. 2 a section on the line 2-2 of Fig. 1. I Fig. 3 is a plan of the underside of the upper portion, and

' Fig. 4: a section on the line elfff of Fig. 3.

Fig. 5 is a side elevation of the whole lid.

Referring to the drawings 1 designates the upper portion of the lid which has a recess 2 on its underside against which the rings 3 of the lower portion rest. The poker hole 5 `must be arranged over the cavity 6. Communicating passages 7, 8, 9, 10 and 11 leadr to the chamber 12 in the boss 13 through which the outlets 14 are arranged. Holes 15v its peripher i,

.ea-ch having opening of each of the vsuccessive Vdiametrically opposite the opening in each ring V'whereby labyrinth passages e are formed leading from said inlet opening to the` center of the facing member, and a `chamber at the-center lof said facing memare provided in both the upper and lower portions 1 and may be held together by rivets or'other suitable means.

The method of operation of my lid is as followsz Y v Air enters through the poker hole the cavity 6 and passing aroundv the rings 3 in the passages 7, S, 9, 10 and 11beconies gradually heated fas it reaches the vcentral chamber 12. The air is -then drawn down through the outlets 1a over the top of the AssIGNon To Tiroivins Barns; on TORONTO,

a so that the said portions 5 into s fire', and distributed substantially evenly in all directions. y

If desired any other form of inlet may be employed instead of the poker hole as shown in the accompanying drawings.'

. vsired result obtained.

Having thus described my invention what 1v claim and desire to secureby Letters Patent is: y

1. An air heating stove lid including a plate provided with an inlet opening near a facing member secured to the underside of said plate and covering the air inlet opening, a series of coiicentrically arranged rings integral with said facing member and abutting said plate, said rings but a single opening and the rings being ber and having one vforaminous wall adjacentJ the fire to direct the heated air downwardly into the re.

2. An air heating stove lid including a plate provided with an inlet openingVV near its periphery, a facing member secured. to the .underside of saidv plate and coveringl the air inlet opening, a series of ooncentrically arranged `rings integral with said facing member and abutting said plate, said rings each having but a single opening andthe opening of each ofthe successive rings b eing diametrically opposite the opening in each adjacent ring whereby labyrinth pas-k sages are formed leading from -said inlet opening to the center of the facing member, a deflector partition connecting the outside p But for the` usual stove the area thereof is ample, and' wail nf sad facing member wim he innerinesf ring at a point dametlically opposite the opening in the latter to form /Wo labyrinth passages, one on each side ofthe center line of said facing membel` and each leading to the center, and a chamber at the center of said facing member and having one orzunneus Wall adjacent the re to dyect The hea/ind an" downwardly lnto the ire.
